Hello
Well since I'm a beginner in Matlab i have a question aboute ploting the graph. How can I merge two graphs into one ? Since i have function test(x,h) and function test2(x,h) both of them plotts in a two separate graphs. How do i do if i want to see both of them in a single graph ...

I would appreciate it if you could show your work.
Thanks in advance.
I just want to know what is the difference on how to find Average velocity and Average speed when I try to find it in Velocity-Time graphs
Also how do you find distance traveled and displacement in these velocity-time graphs.
Thanks in advance for your help.

How can you prove that a cubic graph with a bridge cannot be 3-edge colored?
I guess one could try a proof by contradiction, so we assume a 3 edge coloring is possible for such a graph. But then I am not sure in which direction to continue. I have tried to draw such graphs, and clearly...

e.g. I want to find y when x is at pi/2 for the graph y=cos pi x. Why does pi/2 have to be expressed as a 'normal' (for want of better word) number (3.14/2) and not as 90 degrees (180/2) like you would for a graph without a pi in it
e.g. cos x
For cos x, if x is at pi/2, then I just put in...

Well, I know that in some few special cases It is easy to prove that 2 graphs can not be isomorphic. for example if they gave us two graphs that one of them were bipartite and the other were not, we can state that if the 2 graphs were isomorphic, then they would've had same mathematical...
